Function
function
Involved in the intramitochondrial synthesis of acylcarnitines from accumulated acyl-CoA metabolites. Reconverts acylcarnitines back into the respective acyl-CoA esters that can then undergo beta-oxidation, an essential step for the mitochondrial uptake of long-chain fatty acids and their subsequent beta-oxidation in the mitochondrion. Active with medium (C8-C12) and long-chain (C14-C18) acyl-CoA esters.
Catalytic activity
- (5Z)-tetradecenoyl-CoA + (R)-carnitine = O-(5Z)-tetradecenoyl-(R)-carnitine + CoA
- (R)-carnitine + (9Z)-octadecenoyl-CoA = O-(9Z)-octadecenoyl-(R)-carnitine + CoA
- (9Z)-tetradecenoyl-CoA + (R)-carnitine = O-(9Z)-tetradecenoyl-(R)-carnitine + CoA
- decanoyl-CoA + (R)-carnitine = O-decanoyl-(R)-carnitine + CoA
- dodecanoyl-CoA + (R)-carnitine = O-dodecanoyl-R-carnitine + CoA
- eicosanoyl-CoA + (R)-carnitine = O-eicosanoyl-(R)-carnitine + CoA
- (R)-carnitine + octadecanoyl-CoA = O-octadecanoyl-(R)-carnitine + CoA
- octanoyl-CoA + (R)-carnitine = O-octanoyl-(R)-carnitine + CoA
- tetradecanoyl-CoA + (R)-carnitine = O-tetradecanoyl-(R)-carnitine + CoA
